I think it's very difficult to make a good crafting game, where crafting is at the heart of the game.
However, your game could fit nicely as a mini-game within a much larger game that has crafting in it.
You have many good ideas, that, IMO deserved more development!
The platforming part is a nice idea, but it's repetitive and lacks challenge.
The crafting part is cool, with all the ways you can manipulate the ingredient. But unfortunately, it fades quickly because we are making the same ingredients over and over. The issue here is that you don't have any systemic gameplay. That is, anytime you want to add content for the player, you have to code a feature.
Ways to introduce systemic gameplay could include: fine tuning the cooking of an ingredient with increasingly tight margin, procedurally generated recipes, or stuff like this... But I agree it's very tough to make under sharp time limit.
In all cases, you can see you definitely put some hard work here, and that's great :)
Good luck for the jam!
